Abstract

In a power system for a vehicle, the line segment L connecting between the center O of a driving shaft (speed change shaft) of an oil hydrostatic non-stage transmission and the center O of a ball screw (ratio change driving shaft) of a ratio change mechanism is set parallel to the mating plane P of the crank case and the cylinder block, while the axis C of a detecting shaft is disposed coaxially with the turning axis C of a swash plate holder orthogonal to the line segment L, and, in this condition, a ratio detecting sensor is bolted to an upper wall. Wherein the axis C of the detecting shaft is set parallel to the cylinder axis C , and the machining axis for a crank chamber and the machining axis for a fitting portion for the ratio detecting sensor are set parallel to each other.
